Hi everyone,

 

I know that there is a original feed where this is discussed but there is no clear answer so, please could someone tell me what users will experience if they will only have Teams license assigned but not Exchange, SharePoint or any other licenses?

 

We will be piloting this application for a customer in Office 365 without any other services initially and I would like to know the limitations.

 

Many thanks!

Some info from the docs:

 

Out of the box, a team created in Microsoft Teams will create an Office 365 Group with the associated SharePoint Online site complete with a document library, an Exchange Online group mailbox for the Group which will be used by Teams to store information—such as meeting invites.

 

  • SharePoint Online is required to share and store files in team conversations.
  • OneDrive for Business is required to share and store files in private chats.
  • If users aren't assigned and enabled with SharePoint Online licenses, they don't have OneDrive for Business storage in Office 365. File sharing will continue to work in Channels, but users are unable to share files in Chats without OneDrive for Business storage in Office 365.
  • Security and compliance features like eDiscovery, Content Search, archiving, and legal hold work best in Exchange Online environment. For channel conversations, messages are journaled to the group mailbox in Exchange Online, where they're available for eDiscovery. If SharePoint Online and OneDrive for Business (using work or school account) are enabled across the organization and for users, these compliance features are available for all files within Teams as well.
  • Users who participate in conversations that are part of the Chat list in Microsoft Teams must have an Exchange Online (cloud-based) mailbox in order for an admin to search chat conversations. That's because conversations that are part of the Chat list are stored in the cloud-based mailboxes of the chat participants. If a chat participant doesn't have an Exchange Online mailbox, the admin won't be able to search or place a hold on chat conversations.
  • If you don't have SharePoint enabled in your tenant, Microsoft Teams users are not always able to share files in teams. Users in private chat also can't share files because OneDrive for Business (which is tied to the SharePoint license) is required for that functionality.

Sharing just a summary I put in my deck about Teams that I did for Office 365 Engage:

  • Office 365 suite license required, and prefer but not require Exchange, SharePoint:
    • On-Premises/hybrid must be synced via Azure AD Connect
    • Exchange On-Premises users will have a little less functionality (Connectors)
    • OneDrive (as par of SharePoint) required for private chats
  • Skype for Business is not a pre-req, but SfB users will benefit from interop features:
    • 1:1 IM between Teams and SfB
    • Click to join SFB meetings from the meetings view in Teams
  • Archiving, eDiscovery, compliance via Office 365 Security & Compliance Center:
    • Exchange group mailboxes for team chats and events, user mailboxes for private chats
    • SharePoint / OneDrive archiving for files

Hi Juan,

Our tenant is in Hybrid state. We have all our mailboxes in On-Premises. Still we would like to implement Teams. what are the implications using Teams without a cloud mailbox?
